【问题描述】：
所以我已经使用 Passport.js 成功实现了用户身份验证。
现在我正在尝试实现一个用于重置密码/确认帐户/等的随机 URL 生成器。但我似乎无法通过 Sequelize 引用数据库表。
如何在 Sequelize 中在定义它的模块之外引用已经定义的模型？
在下面的代码中，user 是通过 function(passport, user) 传递的。在 server.js 中为其调用添加第三个参数（例如 require('./app/config/passport.js')(passport, data.user, data.hashedURL) ）并不能解决问题。
以下是我认为的相关部分。如果需要，我可以发布更多。错误点在下方passport.js 模块中用箭头表示。
非常感谢您提供的任何启示！

【问题讨论】：
-
尝试 db.models[modelName] 或 db[modelName]。您正在从 /app/data/index.js 导出 db，因此您可以从那里获取它
-
就是这样！谢谢一百万
